[sergiobenrocha2]

Trying to load Kirby - Tilt 'n' Tumble (USA) in gambatte core, and I got a segfault. Tested in Linux and Android.

Compiled with DEBUG=1:

Can you test this again? Gambatte libretro should now be as up-to-date as upstream.

[Oggom]

It's an upstream issue. The segfault happens because Gambatte doesn't support the mapper used in this game (MBC7).

VBA-M can handle this game, you can assign buttons to the motion control. Is it possible to backport it?
